A method for the detection and treatment of disordered breathing during sleep
employs
an artificial neural network (ANN) in which data related to breathing gas flow
are analyzed. A respiratory circuit is established by connecting the patient to
a continuous positive airway pressure (CPAP) system with pressurized breathing
gas supply, the gas flow in the circuit is periodically sampled, one or several
cepstrum parameters distinctive of various breathing patterns are periodically
calculated; the parameter values are periodically fed to an ANN trained to recognize
breathing patterns characteristic of sleep disordered breathing and are analyzed
in the network, the CPAP pressurized breathing gas supply is controlled in response
to the ANN output. Also disclosed is a corresponding apparatus.
